To all whom it may concern: 7

- Beit known that I, FRANK W. EDWARDS, a-citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have'inventeda certain new and useful Improvement in Sight-FeedLubricators, of which the following is a full, clear, and exact description.

. This invention relates to sight-feed condensation displacement lubricators, and more particularly to. such lubricators when used with down-drop feeds for supplying lubricant under steam pressure to the flanges "reissued October 8, 1912, 952,515, March 22,

of locomotive driving wheels;

The invention is herein 'illustratedand explained in connection with a four -feed lubricator, having down-drop feed tips, for use as a flange oiler, but it is to be under stood that the principle of the invention and the mechanism by which it may be practically applied are applicable to other types of lubricators and to lubricators for other purposes irrespective of the number of feeds.

The invention is designed, among other things, to utilize the short, thick, stocky ob servation glasses of my Patents Nos. 13, 174

1910,953575, Mal-@1129, 1910, 1,009,290, November 21, 1911, 1,032,662, July 16, 1912, and and application Serial No. 650,39d, filed September 20, 1911, and also to extend the principle of protecting these glasses against exposure greater than 'neces'saryto give a clear field of vision to the user. 7

Other objects of the invention will appear in theeXplanation thereof following.

Without thereby intending to limit theinvention or the scopeflof the claims herein, the invention may be said to consist of a lubricator having one or many one-piece I sight feed bodies, pockets or packing cases 'of peculiar construction, in which the obser vation glasses are inclosed and held, and having openings or windows through which the feed of the oil may be seen, and means to connect the pockets with the oil-bowl and the parts to Which the oil is to be supplied, and with the steam supply, as I will proceed now to explain and finally claim.

Specification of Letters Patent. Sept, 14,,- 1915, Application filed April 16, 1915. Serial No. 21,729.

In the accompanying drawings illustrat mg the in-vention,-'in the several figures of which like parts are similarly designated, Figure 1 1s a perspective view Fig-. 2is a front elevation, partly in section; Fig. 3 is a side elevation, partly in section, and Fig. 4 is-a horizontal section on line IV, of Fig. 2, showing the invention applied to a fourfeed flange oiler. Fig. 5" is a side elevation of the lower steam ccmnection. Fig; 61s a view of a modified form of twin pockets, one pocket being in elevation and the other in section. Fig. is a horizontalsection on line VII of Fig. 6. Fig. 8 is a vertical section on line VIII of Fig. 6; Fig. 9 is a side elevation, and Fig. 10 is a rear end view of the steam connection'used with the pockets of the form shown in Figs. 6', 7 and 8.

Ihe oil-bowl 1, its filler plug2, draining means 3, condenser 4, and condenser valve 5;may be of any usual or approved construction.

6 is a fitting or T adapted to be connected with a pipe 7 by which steam is received from a suitable source of supply, such as the locomotive steam boiler, a choke 8 being interposed between the fitting and the steam pipe 7. This fitting is connected with the condenser, as by a coupling 9, and with the steamcirculating pipes 10'. A valve 11 is interposed in the fitting between the steamor boilerconnection 7 and the steam circulating pipes, for controlling the admission of steam into the condenser and to the steam circulating pipes.- These steam circulating pipes enter fittings or elbows 12 which are provided with outlets 13, and these outlets are connected with thesight feed pockets, bodies, or packing" cases 14 so as to deliver steam to the discharge ends of these pockets not only to carry. the oil or lubricant to its destination, but also, oil'er, to forcibly project the oil against the wheel flanges. In order to avoid repetition and forthe sake of uniformity and conciseness the parts 14 are hereinafter referred to as pockets. i

As shown in Fig. 2, the discharge or delivery pipe 15 is connected with the pocket by a coupling 16 in which is interposed a in the case of a flange shown, see Fig. 3, but it is to be understood that one isused for each pocket, and, obviously, any other delivery device may be used to suit the purposes for which the'lubricator is employed. The steam circulating pipe elbow 12 may have an extension 19 to receive a suitable bolt-2O for rigidly V connecting the elbow and pocket with the oil-bowl. The pockets 1A are bottle-shaped, and each has an ,open bottom and top, and the bottom is provided with an internal screwthread 21 orother suitable means to receive a screw-plug 22 or other appropriate closure, and thetop or neck of the bottle is likewise screwthreaded to receive a hub 23 Which carries the oil feed valve 2 1. Inside andbelowthe neck is a web 25 having a screwthreaded hole to receive the down-drop feed tip 26. Below this web is a recess 27, and below this recess is a shoulder 28 whence the diameter of the pocket extends toythe bottom substantially uniformly, excepting that about the middle of the body are windows or openings'29 slightly offset from the inside diameter. These windows are arranged around the pocket so as to admit light into the pocket from all directions.

' The observation glass 30 may be of any one of the various types illustrated in the patents above referred to, or any other ap-v proved style, preferably short, thick and stocky, and it is inserted longitudinally in the pocket with the washer 31 and gasket 32. arranged adjacent to its upper shoulder and between such shoulder and the shoulder 28 in the body; 33 is a gasket and 34 a washer arranged on the lower shoulder of the glass and engaged by the packing stem.

head or cup 35 which is provided with the rim or ledge 36 to receive and engage the washer and gasket. This cup 35 is mounted upon or is made as a part of the packing stem 37 which is adjustably supported in the screw-plug 22 and provided with a squared end 38 or other means by which it may be turned within this screw-plug. The cup or head 35 is'provided with any number of openings 39 for the escape of the oil into the bottom of the pocket, whence, as previously described, it is distributed to the points of application. As will be seen, the

pockets may be made in pairs or as twins, and this is one of the features of novelty herein. As thus made, the pockets are connected in pairs by a transverse pipe 40. and this pipe 40 is provided with a nipple or arm 41 arranged about midway between the pockets. By means of the extension coupling 42, the pockets are connected with the oilbowl in such way that the displaced oil may overflow through the extension coupling a2 and nipple 41 into the down-drop feed tip 26. The pairs of pockets are connected also at or near their bottoms, as by the steam pipes ortubes 13, which-open into both of the pockets of the pairs and areconnected:

with the steam circulating pipe elbow. When four points, or places, or objects, are to be lubricated, the pockets are located in pairs on opposite sides of the oil-bowl, as

.indicated more'sparticularly in Figsal, 3

and 4. 7

Referring to Figs. 6 to 10, it is noted that in addition to the features above described, the two pockets comprising each pair may be connected by ahollow vertically arranged as just described provides forthe gradualheating of the glass within the sight feed body, and in a more even way than when the steam is admitted directly at the bottom of the glass as first described. Otherwise than as stated, the modified form of pocket last described is essentially the same as that first described: I

As distinguishing from the one-piece packing case of my patents referred to, it is to be noted that the bottle-shaped pocket of the present invention has its upper end shaped to receive the upper packing of the glass and that the pressure to compress the gaskets at top and bottomof the glass is and thence into the cross.connecting tube.

As the steam passes into this connecting tube, it is distributed to both of theoil delivery pipe connections into which it passes through the choke valves and thencefiows down to and through the flangenozzles to the place of use. The-condenser valve 5 is then opened, and the feed valve regulated V the bottom of the tom of the pocket and tion glass adjustably.

the water of condensation passing from the condenser to the bottom of the oil-bowl and displacing the oil in the usual way, whence it flows to the feed tips and. thenceescapes drop by drop into the observation tubes or glasses. As the oil reaches the bottom of the sight feed glasses, it comes into contact with ing stem and thence escapes through'the holes 39. As soon as the oil passes through these holes it comes directly into line with the steam flow and is carried by and with the steam in both directions through the chokes 17 into the oil delivery pipes and thence out through the flange nozzles.

The operation'of the modified form of the pockets or bodies is substantially the same as that just described.

By the construction described, a very serviceable lubricator is produced and considerable economy in fittings, as well as in parts to be repaired or replaced, is effected. The

connection of the pockets with the oil-bowl at the top by the extension coupling and the use of the steam-pipe elbows fixed to the oil-bowl makes a rigid and compact construction, which also presents readily accessible means for assembling, dismemberment and repairs.

()f course, it is understood that the invention is applicable to a single feed lubricator or to a multiple feed lubricator; and the use of the invention, obviously, is not restricted to flange oilers.
